[PATCH v3 00/19] xen/arm: mm: Remove open-coding mappings

[Julien Grall <julien@xxxxxxx>]

From: Julien Grall <jgrall@xxxxxxxxxx>

Hi all,

This series was originally sent as "xen/arm: mm: Add limited support
for superpages" [1] and finally has grown enough to remove most of
the open-coding mappings in the boot code.

This will help to:
    1) Get better compliance with the Arm memory model
    2) Pave the way to support other page size (64KB, 16KB)

The previous version was spent a few months ago. So I have decided
to remove all the acked-by/reviewed-by tags.

Cheers,

[1] <20201119190751.22345-1-julien@xxxxxxx>
